Introduction to this section:

This section continues to learn the controls for the adapter class, this time with the Autocompletetextview (auto-complete text box),
I believe the careful you found, and adapter to the side of the control, you can define the item's style, right!
or the layout of each item ~ How to play on how to play ~ Well, words do not say, start the content of this section ~
Yes, put the official api:autocompletetextview.

1. Related properties:

• android:completionhint: Set the tip title in the drop-down menu
• Android:completionhintview: Show drop-down menu in the definition prompt view
• android:completionthreshold: Specifies how many characters the user will enter at least to display a prompt
• Android:dropdownanchor: Sets the anchor component of the drop-down menu, if no property is specified,
  The TextView will be used as the Anchor point component
• android:dropdownheight: Setting the height of the drop-down menu
• android:dropdownwidth: Setting the width of the drop-down menu
• Android:dropdownhorizontaloffset: Specifies the horizontal spacing between the drop-down menu and the text
• android:dropdownverticaloffset: Specify vertical spacing between drop-down menus and text
• android:dropdownselector: Set drop-down menu click Effect
• android:popupbackground: Setting the background of the drop-down menu

In fact, there's a multiautocompletetextview(auto-complete text box with multiple hints)
And this Autocompletetextview function is similar, attributes are the same, specific differences in where,
We're going to experience this in the code below-and the other two are all word matches, like, Piggy Pig:
You input small and will prompt the pig pig, but the input pig----but will not prompt pig pig!

2. code example:

Run :

Implementation Code :

Here is not the custom layout, directly with Arrayadapter to achieve it!

Layout file:activity_main.xml:

<linearlayout xmlns:android="Http://schemas.android.com/apk/res/android"  Xmlns:tools="Http://schemas.android.com/tools"android:layout_width="Match_parent"  android:layout_height="Match_parent"android:orientation="Vertical"  Tools:context=". Mainactivity ">                        <autocompletetextview   Android:id  = "@+id/atv_content"  android: Layout_width  = "match_parent"  android:layout_ Height  = "48DP"  android:completionhint  = "Please enter search content"  android:completionthreshold  =< Span class= "Hljs-value" > "1"  android:dropdownhorizontaloffset  = "5DP" />     <multiautocompletetextviewandroid:id="@+id/matv_content"android:layout_ Width="Match_parent"android:layout_height="48DP"android: Completionthreshold="1"android:dropdownhorizontaloffset="5DP"android: Text="" />                                                </linearlayout>

Mainactivity.java:

 Public  class mainactivity extends appcompatactivity {    PrivateAutocompletetextview atv_content;PrivateMultiautocompletetextview matv_content;Private Static Finalstring[] data =Newstring[]{"Piggy Pig","Puppy dog.","Small Chicken"," kitty Cat","Little Mimi."};@Override    protected void onCreate(Bundle savedinstancestate) {Super. OnCreate (Savedinstancestate);        Setcontentview (R.layout.activity_main);        Atv_content = (Autocompletetextview) Findviewbyid (r.id.atv_content);        Matv_content = (Multiautocompletetextview) Findviewbyid (r.id.matv_content); arrayadapter<string> adapter =NewArrayadapter<string> (mainactivity. ThisAndroid.        R.layout.simple_dropdown_item_1line, data);        Atv_content.setadapter (adapter); Arrayadapter<string> Adapter2 =NewArrayadapter<string> (Getapplicationcontext (), Android.        R.layout.simple_dropdown_item_1line, data);        Matv_content.setadapter (adapter); Matv_content.settokenizer (NewMultiautocompletetextview.commatokenizer ()); }}

part of the Code Analysis :

1. Android:completionthreshold= "1": here we set the input a word to display the prompt
2. android:completionhint= "Please enter search Content": This is the text displayed at the bottom of the box, if you feel ugly
   You can set a view! Android:completionhintview
3. Android:dropdownhorizontaloffset= "5DP": Set the horizontal margin to 5DP
4. Matv_content.settokenizer (New Multiautocompletetextview.commatokenizer ());
   Settokenizer is to set the delimiter for it
